Pretty Little Liars' Alison is not safe from death, particularly not in prison.

What Does Mike Montgomery Know About Mona On 'Pretty Little Liars'? Writer Teases Upcoming Reveals

The Queen of Mean is currently behind bars for Mona's (Janel Parrish) murder, but that doesn't mean she will be safe - not from 'A' and probably not from her new prison pals.

"I heard people are afraid we're going to kill Alison. And nobody's safe in our world," executive producer Marlene King told E! Online. "Nobody and that's just the cost of living in Rosewood. Nobody is safe."

While Alison (Sasha Pieterse) fights of her enemies, she may also have to fight off false accusations. Nothing is ever as it seems on Pretty Little Liars, and there is still a chance that Alison didn't commit the crimes the Liars have pinned on her.

If someone could just uncover Mona's missing remains, perhaps the culprit can be definitively pinned down. Luckily, one intrepid Rosewood resident will mange to unearth the body before season 5 comes to an end.

"There certainly is a trail that leads to remains," writer Joseph Doughtery ("Through a Glass, Darkly," "No One Here Can Love or Understand Me") teased, according to People. "And that will happen in the winter season."
